I have plenty of room down the sides of the house for slimline tanks but you just cant beat the in-ground as you get to capture all of the roofs run off.... you also don't lose the space having an in-ground tank... so many positives on doing it! very nice, I'm impressed Re: Underground Water Tank in front yard 22Feb 16, 2013 8:46 am Barking dogs, chain saws, bullet holes in the water tank ! Sounds like you were living in the Bogan Valley Redman ! From my sustainability links sticky at the top of this forum are these two links... A good ( as in simplest ) rainfall calculator for finding out how much water you can collect from your roof in one month ( or year ) in your area. http://stratco.com.au/products/rainwate ... rtanks.asp Just type in your roof area , punch in your postcode and voila. Edited 11/02/13 Thanks to Bashworth ( again ) Here is an almost as good calculator to find out which size tank best suits your needs according to your postcode , catchment roof area and daily use. http://tankulator.ata.org.au/index.php Added 10/11/12 Stewie Re: Underground Water Tank in front yard 23Feb 16, 2013 12:44 pm Just be aware that a tank will only collect water from the roof areas the downpipes feeding the tank harvest. The harvest yield will also not be 100% and yield losses depend on several factors including the climate (initial evaporation), type and slope of roof in relation to the harvest area and predominate direction of weather, the rainfall frequency and duration, surrounding trees that may create a rain shadow, first flush size and type if fitted, the size of the tank...the list goes on and on. "Calculators" do not and cannot factor these variables. It must also be remembered that the tank's overflow capacity must be equal to or greater than the inflow capacity. The overflow outlet must also be accessible when the top meshed inlet is removed. Overflow mesh will become restricted in time and if there is a storm and the overflow pipe cannot discharge the excess inflow once a tank fills, the tank will overtop. If you cannot reach the overflow mesh, you will have to remove the overflow pipe to access the mesh. Regulations are very poor in regard to an adequately sized overflow and is why so many QLD tanks overtop. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.
